Rose plant named `Meiparnin`

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive very large blossoms that are Cream Yellow and bordered and suffused with light Carmine Rose. Such blossoms additionally exhibit a subtle peach-like fragrance. The plant exhibits medium green and bright foliage, as well as good disease resistance. The new variety is particularly well suited for growing as attractive ornamentation in the landscape or for use when forming cut flowers.

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the product of the cross of the `Meicapula` variety(non-patented in the United States) and the `Korav` variety(non-patented in the United States). The male parent (i.e., the pollenparent) was the `Delboip` variety (non-patented in the United States).The parentage of the new variety can be summarized as follows:

    (`Meicapula`×`Korav`)×`Delboip`.

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

(a) forms in abundance attractive very large Cream Yellow blossoms thatare bordered and suffused with light Carmine Rose and possess a subtlepeach-like fragrance,

(b) exhibits a semi-erect growth habit,

(c) forms attractive medium green and glossy foliage, and

(d) exhibits good disease resistance.

The new variety well meets the needs of the horticultural industry andis particularly well adapted for use as an attractive ornamental plantin an outdoors environment or for cut flower production.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, and cuttage. Asexualpropagation by the above-mentioned techniques in France has shown thatthe characteristics of the new variety are stable and are strictlytransmissible by such asexual propagation from one generation toanother.

The new variety has been named the `Meiparnin` variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed during Junewhile budded on Rosa froebelii understock and growing outdoors at LeCannet des Maures, Var, France. Dimensions in centimeters are indicatedat the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of two year-old plants during June while budded on Rosafroebelii understock and growing outdoors at Le Cannet des Maures, Var,France. The coloration in common terms precedes reference to the chartin some instances.
